Abstract: Various embodiments related to three dimensional printers, and reinforced filaments, and their methods of use are described. In one embodiment, a void free reinforced filament is fed into an conduit nozzle. The reinforced filament includes a core, which may be continuous or semi-continuous, and a matrix material surrounding the core. The reinforced filament is heated to a temperature greater than a melting temperature of the matrix material and less than a melting temperature of the core prior to drag the filament from the conduit nozzle.

Abstract: In a method for additive manufacturing, a multi-strand core reinforced filament including a flowable matrix material and substantially continuous reinforcing strands extending in a direction parallel to a length of the filament is supplied. A first consolidated composite swath of a height less than ½ the width of the filament is deposited in a first reinforcement formation including at least one straight path and at least one curved path against a deposition surface, and a second consolidated composite swath of a height less than ½ the width of the filament is deposited in a second reinforcement formation against the first consolidated composite swath. Each deposition flows the matrix material and applies an ironing force to spread the reinforcing strands within the filament against the underlying surface and/or previously deposited swath.
